T0 all whom it may concern.-

Beit known that l, FREDERICK Romain, of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Carbonating Apparatus; and l do hereby declare the following to be a full, clear, and exact dcscription of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to improvements 1n the art of carbonating liquids; and it is the purpose of my invention to provide an apparatus of-this character whichis capable of producing the carbonated or aerated li uid 'directly from the gas and water or other liquid which may be employed through the medium of a commin'gling chamber which is of such a construction that a thorough impregnation is secured without the necessity of employing mechanically-agitated devices such as are often found necessary in other apparatuses.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the speci- '.tication.

in the drawings, Figure l is a diagrammatic view showing the method of connecting up an apparatus embodying my invention; and F ig. 2 is a sectional view thrmigh the commingling-chamber, showing the interior construction and arrangement of its parts.

ASimilar reference-numerals in both ligures indicate similar parts.

Heretofore in the process ol" carbonating liquids it has been customary to lead the water and gas se arately to a mixing-chainber which usua y contains some suitable agitator through the operation of which the water is impregnated with the gas, some systems employing a supplemental device, such as a series of plates over which the partially-- mixed liquid 1s assed in thin iilms to en able it to absorb sufiicicnt gas; but those devices are not only very expensive and complicated, but they do not thoroughly impregnato the liquid with the gas; and it is the purpose of my present invention to simplify the construction and operation of the apparatus and te secure a more perfect oarbonlzation of the liquid.

The present embodiment oi my invention comprises generally the rerigerating-chainber 1, within which is preferably iocated the coil 2, through which 'water from the supplypipe 3 passes in order that its temperature may be reduced before it reaches the gas, this supply-pipe 3- connecting, preferably", with an ordinary service-pipe which is usually supplied under pressure. This coil 2 eonneets at its opposite end with the comininglingchamber 6 at the connection 7, and adjacent to this connection 7 is provided a similar connection 8, with which is connected the gas-supply pipe 9, which leads to the connection l0 of a pressure-re fulator 1l. This .chamber 6 embodies genera iy a hollow cylindrical casing l2, to one end of which are connected the littings 7 and 8 and at the unposite end is connected the fitting i3, which connects by the pipe 14 with a settling receptacle or reservoir l5, to the op osite end of which is connected pipe 1G, W lich leads to the draft-arm 1,7 of the soda-fountain or other dispensing apparatus.

.lvtfithin the casing l2 is mounted a tube le, which is preferably arranged concentrically within the casing and connects at 'one end 'with the iitting 8, which connects with the gas-simply pipe 9, such construction 'forming annular chamber which surrounds this tube and forms a communication between the water-supply pipe 2 and the pipe i4. 'll he tube l is provided at suitable intervals with orilices it), and over the tube adjacent to each oril'icc is litted a sleeve T20, each having a portion adapted to snugly fit the tube to retain it in operative position and provided with a hollow annular extension 2l, which is comparativelythin, and it lorms an annular space 22 between it and the tube '1.8, the sleeve 20 being so adjusted on the tube that the annular chamber 22 will connnunicate with the corresponding oriiice 19 of the tube, those portions of the sleeve 20 in which are formed the annular chambers 22 being so arranged that vthe openings in these chambers are directed away from the fittings 7 and S and toward the iitting 13 at the opposite end ol' the chamber for a purpose that will presently appear.

Any suitable source of gas-supply may be employed but l prefer to use the ordinary receptacles or tanks 23, which are charged with vhigher initial pressure than that of the liquid to be carbonated, and to these tanks are connected the pipes 24, which are provided with ICO semer 33 I claim as Inynvention 1. The combination with sources of liquid and gas supply under pressure, and regulating means for maintaining a predetermined ratio between the pressures of the liquid and gas, of a carbcnator for mixing'the liquid and gas embodying a hollow casing having communication at one end with the source of liq udlsupply and provided with a discharge at its opposite end, said casing forming a passage for the liquid during carbonization, and a nozzle inclosed by and spaced from the-walls of said casing and communicating with the source of gas-supply', said nozzle having a contracted gas-discharge orifice, and a sleeve on the nozzle having an enlarged interior eXM pansion-chamber for receiving gas from the discharge-orifice and permitting it to expand, the said chamber of the sleeve 'having an enlargeddischarge-oriice fr -spreading the gas and introducing itin the form of a film of enlarged surface and reduced pressure to the liquid contained in the casing.

` I2. A carbonator embodying a hollow cascommunicating at one end with a source of i quid-supply and having a discharge at its opposite end', forming a passage for the liquid to be carbonated, a tube inclosed therein and spacedfrom the Walls of the casing to form a mining-chamber, said tube being in communication with a source of gas-supply under pressure and having a discharge-orifice therein, and a gasegrpansion and temperature" equalizing chamber embodying a sleeve arranged between the nozzle and the outer casing having a hollow extension with thin Walls spaced from the nozzle and projecting over the discharge-orifice to form an enlarged eX- pansion-cliamber, the thin walls of which are in contact with the liquid, whereby gas under pressure issuing from the oriiice into the ex pansion-charnber Will expand into an annular film of enlarged surface the temperature of which will be equalized with that of the liquid before mixture through the thin Walls of the expansion-chamber;

3. in a carbonator, the combination with a hollow casin(r communicating at one end with a source of liquid-supply and having a discharge at its opposite end, of tube inclosed within the casing and spaced from the Walls thereof to forni a mixing-chamber, said tube being connected to a source of gas-supply under pressure, and having a series of dischargeorifices spaced lengthwise thereof, and a series of" ass-expansion and temperature-equalizing c` ambers spaced lengthwise of the gastube for the discharge-orifices, each ernbodying a sleeve having thin Walls spaced from the tube forming an enlarged.expansion-chamber for receiving the gas under high pressure from the oriiice, expanding it into a film of low pressure and enlarged surface and intro` ducing it to the liquid in such form, the outer surface of the thin walls of the sleeves being in contact wi th the liquid and acting to equalize the temperatures of the latter and the gas before mixing.
